TUBULAR BOILER.

SPECIFICATION forming part or Letters Patent No. 618,556, dated January31, 1899.

Application filed May 4, 189 8- Seiial No. 679,713. (No model.)

To all whom it may concern:

Be it known that I, ANTHONY BINK, a citizen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and useful Improvements in TubularBoilers; and I do declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to that class of boilers which are composed oftubes wherein the water is contained; and my object is to fur- Figure 1is a right-hand side elevation of my improved boiler with the jacket insection. Fig. 2 is a rear end elevation of the same, showing the jacketin section. Fig. 3 is a detached detail view of one of the sectionalpipes, showing the method of connection.

Similar figures of reference indicate corresponding parts in the severalviews.

Apipe 1, of suitable dimensions, is arranged vertically at each cornerof the space wherein the fire-box is contained. The said pipes 1 areconnected at each side of the boiler by a pipe or drum 2, which extendslongitudinally below the side of said fire-box. Drums 3 are arranged oneon either side above the pipes l, and said pipes 1 at their upper endsare attached to and communicate with the said drums 3 at either end ofthe same. A steamdrum 4 is mounted above the drums 3 and communicateswith each of said drums 3 by means of pipes 5, which may be inserted inany approved manner.

The fire-box of my boiler; is composed of pipes of a lesser diameterthan the pipes 1 and 2, arranged in upright frames, as shown in Fig. 3,and located transversely and side by side beneath the drums 3, saidframes each having a nipple 6 inserted in an opening in the pipe 2,which nipple is adapted to receive the parts of a union-coupling 7. Anipple S, which is attached in one end of a T joint 9, is adapted toreceive the parts of the unioncoupling 7, thereby rendering the jointcomplete. A pipe 10 is arranged vertically in the T 9, and its other endhas a T 11 attached thereon, which receives a pipe 12, arrangedhorizontally therein, said T being arranged with a plug 14 in its freeopening opposite the pipe 12 for the purpose hereinafter set forth. Theother opening of the T 9 is adapted to receive a pipe 13, arrangedhorizontally beneath and parallel with the pipe 12, said pipes 13 of allof the sections when arranged in position forming the bottom or grate ofthe firebox, said pipe 13 having a T 15, with a plug 16 therein, similarto the T 11, attached on the end of the same. A vertical pipe 17 isinserted in the T 15 and arranged parallel with the pipe 10. The upperend of the pipe 17 has a T 18, having a plug in one of the openingsthereof, attached on its free end, said T 18 being adapted to receive anipple 19, on which a T 20 is arranged, with a nipple 21 inserted in itsopposite opening. The ends of the pipe 12 and nipple 21 are arrangedtogether and adapted to receive a sleeve 22 thereon. 'The T 20 has apipe 23 arranged vertically from the same, said pipe 23 having aunion-coupling 2 1 suitably arranged thereon and being inserted in theopening in the under side of the drum 3.

The above-described pipe-sections are arrangedwith the nipple 6 of eachsection inserted alternately in the pipe 2 on either side, and the pipe23 of each section is inserted in the drum 3, opposite to the pipe 2, inwhich the nipple 6 of that particular section is inserted, therebyproviding a circulation of the water in the pipes from the pipe 2 oneach side to the drum 3 on the opposite side.

The water-glass 25 may be attached in any approved manner. I provide anumber of pipes 26 from the steam-drum 4, which may be used forattaching steam-gage, &c.

The rear end of the fire box is composed of horizontal pipe-sections 27,attached to the pipes 1 by means of T-joints, and are pro vided withunion-couplings 28. At each junction of the pipes 1 and 2 in front afourway joint 29 is arranged with a plug 30 in the opening opposite thepipe 2, and the opening in its under side has a reducer 31 insertedtherein, to one of which reducers suitable pipe connection may beestablished to the injector, (not shown,) and to the other red ucer 31suitable pipes may be connected and used to withdraw the contents of theboiler.

If preferred, the two reducers 31 may be connected together by suitablepipes, as shown in dotted lines, Fig. 2, and fitted with suitablestop-cocks.

My boiler is incased in a jacket composed of two thicknesses of sheetmetal 32, arranged with a suitable space between the-same and a heatnon-conducting material 33, inserted in said space. The bottom 34 iscomposed of sheet metal bolted to the sides and ends. A suitable door 35is arranged in the front end of the jacket opposite the fire-box for theadmission of fuel. Adoor 36 is arranged below the door 35 for thepurpose of removing the ashes and providing a draft. 37 represents thesmoke-stack, which may be of any approved type. The casing or jacket ,ofmy boiler may be built and I prefer to build the same, especially onlarge boilers, in sections, so that any section may be removed, therebyfacilitating the repairing of any part needing attention withoutremoving the entire casing or jacket.

The advantages of my improved boiler are that the pipes l and 2 presentless heatingsurface by reason of their greater diameter and distancefrom the fire. Consequently the water flows downwardly from the drums 3through the pipes 1 into the pipes 2, where it may be distributedthrough the nipples 6 and S into the sections composing the fire-box. Aswill be seen, the intense heat communicated to the pipes 12, 10, 13, and17 causes an upward flow of the water through the pipes 23 into the drum3, from where it flows into the pipe 1, making a continuous circulation.Another advantage of my boiler is that any section of the fire-box maybe removed by means of the union-couplings 7 and 2 1 and by the use ofthe T-joints 9 11 15 18, arranged at the angles of the pipe-sectionscomposing the fire-box. Should the pipes become corroded or clogged, theplugstmay be withdrawn from said T-joints and suitable instrumentsinserted to withdraw the obstruction. Any sediment that may collect inthe pipes 2 may be Withdrawn by removing the plugs 30 and inserting asuitable instrument therein.

By having the fire-box composed entirely of pipe all heat is utilized.

I am well aware that boilers have been constructed of tubes adapted tohold water, and I therefore do not claim that feature broadly; but

What I do claim as new, and desire to secure by Letters Patent, is

1. In a water-tube boiler, the combination of upper and lower drums, anda plurality of upright transversely-arranged frames formed by connectedpipes and connected with the upper and lower drums; the said framesbeing disposed side by side and forming the grate, top" and sides of a'fire-box, substantially as specified.

2. In a water-tube boiler, the combination of the upper and lowerlongitudinal drums, pipes connecting the ends of each upper drum withthe ends of the lower drum below it, and a plurality of upright,transversely-arranged frames formed by connected pipes; the said framesbeing disposed side by side and forming the grate, top and sides of afire-box, and each frame being connected with a lower 1011- gitudinaldrum at one side of the boiler and with the upper drum at the oppositeside of the boiler, substantially as and for the purpose set forth.

3. In a Water-tube boiler, the combination of a suitable casing, upperand lower longitudinal drums arranged in the casing at opposite sides ofthe longitudinal center thereof, corner-pipes connecting the ends ofeach upper drum with the ends of the lower drum below it, a plurality ofhorizontal pipes connected to the rear corner-pipes at intervals in thelength thereof and forming the rear wall of a fire-box, and a pluralityof upright, transversely-arranged frames formed by connected pipes; thesaid frames being disposed side by side and forming the grate, top andsides of the fire-box, and each frame being connected with a lowerlongitudinal drum at one side of the boiler and with the upper drum atthe opposite side of the boiler, substantially as specified.

4. In a water-tube boiler, the combination of upper and lower drums, anda plurality of upright, transversely-arranged, rectangular frames formedby pipes connected at the corners of the frame by joints havingremovable plugs coincident with the pipes; the said frames beingconnected with the upper and lower drums and being disposed side by sideand forming the grate, top and sides of a firebox, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.

ANTHONY BINK.
